If you've ever wondered what it would be like to swim through little caves and run around on the ocean floor, look no further. What's more, its filmed entirely on a GoPro, further proving that you don't need a $5000 camera to make an awesome video.

Filmed on the beautiful North Shore of Oahu, Hawaii. When the summer is here and the ocean on the North Shore is calm, we play in the underwater caves. For the shots when we are running, we would carry rocks that were heavy enough to keep our body weight on the ocean floor. Only our lungs were used to capture the shots; no scuba gear!
